The American Century plant is a member of the Agavaceae family and a "succulent"---a plant with high moisture conten. The perennial makes its home only in California, Texas, Arizona, Hawaii, Louisiana and Florida, in addition to the U.S. Virgin Islands.
The bluish-green hue of the agave Americana Century plant commonly receives attention as the focal point of landscaping efforts. "Makes a great landscape focal point or accent and can be used in pots away from foot traffic. Best in full sun, but can take light shade," according to the Lady Bird Johnson Wildflower Center at the University of Texas at Austin.
Natural enemies of the American Century plant include cold, wintry temperatures, diseases such as crown rot or root rot, and pests such as the agave snout weevil. This bug is known to decimate an agave upon infestation, in addition to making the cactus more susceptible to the various forms of rot.
